ICE OR SNOW PLOW FOR RAILROAD-TRACKS.

SPECIFICATION forming part Of Letters Patent N0. 405,039, dated June 11,1889.

Application filed May 2, 1388. Serial No. 272,552. (No model.)

T0 at whom it may concern.-

Be it known that I, EDWARD LESLIE, of Orangeville, in the county ofDufferin, Prov ince of Ontario, and Dominion of Canada, have invented anew and Improved Ice or Snow Plow Flanger for Railroad-Tracks, of whichthe following is a full, clear, and exact description.

The invention relates toice or snowplows such as shown and described inLetters Patent No. 380,042, granted 'to me under date of March 27, 1888.

The object of the invention is to design an effective ice or snow plow,which will loosen any hardened snow or ice immediately next to thetrack, and a flanger that will remove the snow and ice in proximity tothe inside rail and discharge the same at a sufficient distance from thetrack to prevent it from falling back.

The invention consists in an independent raising and lowering mechanismwhereby the preceding snow or ice plow or the following flan ger may beput into operation either separately or to co-operate, as desired. 1

The invention further consists in providing the snow or ice plowmechanism and the flanger mechanism with an independent device, wherebythe shock or strain consequent upon either the snow or ice plow or theflanger striking an obstructionsuch as a switch-which invariably resultsin either tearing out the obstruction or demolishing the snow plow orflanger, or both, will break, shear off, or tear out such device, thuspermitting the obstruction and the above-mentioned mechanism to remainunharmed.

The invention also consists of certain parts and details andcombinations of'the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the'accompanying drawings, formingapart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is aperspective view of the improvement as applied. Fig. 2 is alike view of the ice-plows and rail-scrapers. Fig. 3 is an enlargedsectional end elevation of part of the same on the line at a; of Fig. 2,and Fig. 4 is a perspective view of the fiangers and their immediateconnections.

The truck A, of any approved construction, is provided with a frame B,having at its front upper end a cross-beam B, carrying the bear ings Bin which is journaled the transverse shaft 0, provided with thecrank-arms O, pivotally connected with the Vertical posts D D, securedto each other by a transverse brace D so as to form a frame D, carryingthe ice-plows E and the scrapers F.

The frame D rests with its rear end against the front ends of thelongitudinal beams B of the truck-frame, and the front ends of the saidbeams B are connected with each other by the brace B and form a guidefor the vertically-sliding frame D. r r On the lower end of each post Dis held a plate G, having a beveled rear edge G, resting against a pin13 secured to the respective longitudinal beam B 'of the truck-frame 13.Next to this plate G is placed the ice-plow E, which extends below theplate G and the post D, and is held close to the inside of therespective track-rail H, and when in its lowermost position extends withits bottom end to within a short distance of the railroad-"ties H.

On the outer face of each plow E is held a scraper F, formed of anLshaped plate, and extending,with its arm F, across the top of the respective rail H when the post'D is in its lowermost position. The arm Fof the scraper F is slightly inclined toward the rear, so as tofacilitate the removing of the snow or ice scraped up by the lower edgeof the said arm F. By means of the said inclined face G of the plow Gand the pin B the ice-plowE and the scraper F are prevented from comingin contact with the tread of the truck-wheels.

The plate G and the plow E are secured to the lower end of therespective post D by a heavy bolt E, and the scraper F is secured by thesmaller bolts E and E to the plow E;

but the bolt E passes through the plow E, and the plate G and is heldinto the post D, while the other bolt E is shorter, and only screws intothe plowE without passing into the plate G or the post D, as shown inFig. 3. Thus when the frame D is in its lowermost position and theapparatus is in operation and the plows E strike against a switch-railor other obstruction in the track, then the force of forward movement ofthe truck A causes the shearing off of the small bolt E and the Ice plowE, scraper F, and plate G swing rearwardly and upwardly, turning on theheavy bolt E as a pivot. A breaking of the switchrails is thusprevented. The bolt E is then replaced by a new one to secure theseveral pieces together, as above described.

On the rear upper end of the frame B is held a transverse beam B,provided with hearings in which is journaled a transverse shaft I,having crank-arms I pivotally connected with the upright posts J,connected with each other near their lower ends by the transverse beam Jso as to form the frame J the latter supports at the ends of the beam Jthe flangers K K, held at an angle to the said beams and formed like ascoop, with the outer open ends extending rearward. The inner closed endof each flanger K is provided with a downward projection K, extendingbelow the top of the respective rail ll, so as to gather up the snow andice between the rails II and loosened by the plows E, before mentioned.The outer ends of the two flan gers K are connected with each other attheir back by a brace K. The outer ends of the flangers K extend aconsiderable distance beyond the outside of the rails H, so as todeliver the snow and ice a suitable distance to each side of the track.On the inner edge of the trans verse beam J 2 are held the verticalguide plates J against which rest the upwardlyturned ends B of thelongitudinal beams B secured to the truck-frame.

To the inner ends of the flangers K K are secured the brackets K Kconnected with one end of the chains L and L respectively, extendingforward and passing over the lower curved ends of the vertical rods Land L respectively, held in suitable keepers 011 the truck-frame B, asis plainly shown in Fig. at. The other ends of the chains L and L extendinwardly toward each other, and are secured to the ends of the plate N,pivoted in its middle to the vertical rod N, held in suitable keepers onthe front of the middle beam of the truck frame B, between the rods Land L Near the outer end of the two transverse shafts C and I are formeddrums O and 0, respectively, on which are secured the chains P and P,respectively, passing rearward and over a drum Q, 011 which they aresecured. This drum Q is mounted to rotate in suitable bearings formed onthe car R in the rear of the truck A, and the drum is operated by achain Q, connecting the said drum with one end of a piston-rod Qsupporting a piston working in the cylinder Q operated by steam or airand under the control of the engineer. On the outer ends of each of thetwo shafts C and I is also secured an arm S and S, respectively, heldinclined to each other and connected with the chains T and T, secured tothe lower end of the vertical lever U, fulcrumed in the middle of thetruck A. A short chain V is secured to the other end of the arm S, andis connected with the frame 13, serving to prevent the arm S and itsshaft I and the flangers K returning to their former position after theflangers are raised.

The operation is as follows: IVhen the ma chine is in the position shownin Fig. 1. and the truck A is pushed forward by suitable means, then theplows E loosen the ice next to the inside of the rails II, so as to forma clear space for the flanges of the following car-wheels to prevent aderailing of the cars. The scrapers F, held on top of the rails ll,remove all snow and ice from the same, so as to clear the rails for thetread of the following car-wheels. The tlangers K K at the rear of thetruck A gather up a large amount of snow and ice located between therails and at their outside, and at the forward motion of the truck thesnow and ice pass through the open ends of the scoop-shaped scrapers andare delivered a suitable distance beyond the sides of the track. \Vhenthe plows E strike an obstruction in the track, the bolts E are shearedoff, as above described, and the plows are thrown upward and rearwardabove the rails II. The truck A is moved beyond the obstruction, thebolts are replaced by new ones, and then the apparatus is again movedforward, as above described. When the flangers K strike an obstruction,the plate N, connected by the chains L L with the said Hangers, isbroken,and the latter are free to swing rearwardly, turning with theirframe J on the crank-arms I of the shaft I. WVhen the obstruction isremoved or passed, then the plate N is replaced by a new one. The plateN is purposely so made that when the flangers or either of them meet anabnormal obstruction the plate N will break about the shaft N, thusleaving both flangers free and avoiding any twist being thrown upon theframe-work of the flanger, which would be the case were one Hanger freeand the other held fast. I purposely make the chains L L and theirconnections with the Y plate and flangers much stronger than the plate Nwhere the same is pierced by the shaft N, and in this way when anobstruction is metit results in freeing both flangers.

hen the operator desires to raise theplows E and scrapers F, he throwsthe lever U forward in the direction of the arrow a, whereby the chain Tpulls on the arm S, thereby turning the shaft 0, so that the crank-armsC swing upward and raise the frame D, carrying the plows and scrapers.The latter are thus raised above the track-rails H, and can clearswitch-rails or frogs located between the rails. hen the obstruction ispassed, the lever U is moved to a vertical position, whereby the frame Dby its own weight slides downward to its former position. The flangers KK are raised above the track by moving the lever U in the reverseinverse direction of the arrow a, so that the chain T pulling on the armS turns the shaft I, and the latter, by the crank-arms I, raises theframe J and the flanger K connected with the said IIO ITS

frame. By moving the'lever U forward or backward I am enabled to throweither the plows E. and scrapers F or the flangers K upward out ofcontact with the rails and hold them in this position, so that only theplows E and scrapers F or the Hangers K, as desired, are'at work.

WVhen the operator desires to raise the plows, scrapers, and flangerssimultaneously, then steam or air is admitted to the cylinder Q so as toraise its piston and piston-rod Q whereby the drum Q is turned and thechains P and P are wound up on the said drum Q. As the chains P and Pare connected with the shafts O and I, the latter are consequentlyturned and raise the frames D and J in a similar manner to that abovedescribed in reference to the lever U.

It will be seen that the several devices are fully under the control ofthe operator, and if the plows E or flangers K should strike an unseenobstruction they operate automatically and without injuring ordestroying the obstruction. Instead of using crank-arms O and I on theshafts O and I, I may employ similar devicessuch as cams, levers, oreccentricsfor raising the frames D and J.

It will be seen that by supporting the frames D and J from thetruck-frame, instead of the car-body, I am enabled to clear the railsperfectly on curves, as the said frames are not affected by the swayingof the carbody or the lateral motion of the car-springs when the carpasses over the curve.

One of the objects of my present invention is to support an ice-plow,scraper, and flanger solely from the truck, and in such a way that thedevices do not receive any motion from the movement of the car-body whenthe same may move in relation to the truck.

My invention is illustrated and is best carried out with the truck-frameand journalboxes for the wheels so arranged that the frame andjournalboxes always move together; but it can be used on either form oftrucks, although on trucks where there is a movement between the frameand journalboxes as close an adjustment of the scrapers and flangers tothe top of the rail cannot be had as can be made in the case where thetruck is so constructed that there is practically no movement betweenthe frame and the journal-boxes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
